High pressure on Wednesday will briefly bring cooler and quiet weather, but things will turn more active later in the week as temperatures trend warmer again.

An embedded well-marked wave will zip through an increasing west-northwest flow towards dawn, and could actually bring a decaying yet possibly gusty line of convection into parts of Central NY first thing in the morning. At the surface, this will also be marked as a pre-frontal trough, which will greatly complicate the forecast for Tuesday...The Storm Prediction Center has placed our whole area into a Slight Risk for severe thunderstorms Tuesday, due to the potential of damaging winds as indicated by strong unidirectional shear of 40-50 knots at 6 km.
